executed to better differentiate between loader-specific errors and kernel-
specific errors (if ever any of either).
This type of functionality hasn't been required before the introduction of the
advanced menu system (r222417). Adding this functionality will help different-
iate errors at the loader-level such as a BTX halt caused by heap exhaustion
and errors that may be involved with executing the kernel (wrong architecture
for example). A user can learn that messages before "Booting..." are related to
the loader(8) environment and it's Forth-ilk, while those after are not
related to loader(8) -- the point that loader(8) has ``left the building''.
This patch also includes a man-page update to color.4th(8) as the color logic
moves to a lower-level (from being included by beastie.4th to being included
by loader.4th).
After noticing a delay between execution of the overloaded "boot" FICL word and
the display of text on-screen, gcooper confirmed that the introduction of a
builtin memory test (disabled by adding hw.memtest.tests="0" to loader.conf(5))
was the cause of the delay.
This patch adds an echo to produce "Booting..." when the overloaded "boot" word
is executed (this includes from the interactive command-prompt on all arches,
from the menu system on arches that run the beastie menu, and even those arches
that run the menu but disable it by setting beastie_disable="YES" in
loader.conf(5)). When loader_color="YES" in loader.conf(5), the same message is
produced but in white text on a blue background (only the letters produced have
this background -- opposed to perhaps the entire line).
upon pmap_enter() to create a mapping within a different address space,
i.e., not the thread's own address space. On i386, this entails the
creation of a temporary mapping to the affected page table page (PTP). In
general, pmap_enter() will read from this PTP, allocate a PV entry, and
write to this PTP. The trouble comes when the system is short of memory.
In order to allocate a new PV entry, an older PV entry has to be
reclaimed. Reclaiming a PV entry involves destroying a mapping, which
requires access to the affected PTP. Thus, the PTP mapped at the
beginning of pmap_enter() is no longer mapped at the end of pmap_enter(),
which leads to pmap_enter() modifying the wrong PTP. To address this
problem, pmap_pv_reclaim() is changed to use an alternate method of
mapping PTPs.

host byte order, was sometimes called with net byte order. Since we are
moving towards net byte order throughout the stack, the function was
converted to expect net byte order, and its consumers fixed appropriately:
- ip_output(), ipfilter(4) not changed, since already call
in_delayed_cksum() with header in net byte order.
- divert(4), ng_nat(4), ipfw_nat(4) now don't need to swap byte order
there and back.
- mrouting code and IPv6 ipsec now need to switch byte order there and
back, but I hope, this is temporary solution.
- In ipsec(4) shifted switch to net byte order prior to in_delayed_cksum().
- pf_route() catches up on r241245 changes to ip_output().

Unlike upstream this has no benefit on FreeBSD.
We know that as soon as the provider is created it is going to be tasted

This should allow to mount a dataset as a root filesystem even if

This adds some overhead to the boot process though.
If the root filesystem's pool is found in zpool.cache, the by default
